How do I view TRTC logs? #
TRTC logs are compressed and encrypted by default with the XLOG extension. You can set setLogCompressEnabled to specify whether to encrypt logs. If a log filename contains C (compressed), the log is compressed and encrypted; if it contains R (raw), the log is in plaintext.

iOS：Documents/log of the application sandbox
Android

6.7 or below: /sdcard/log/tencent/liteav
6.8 or above: /sdcard/Android/data/package name/files/log/tencent/liteav/
